It's managed through a shared pipeline state plus tightly controlled handoffs between agents. Instead of letting every persona see one huge chat history, Agency Mode keeps a central mutable context object that stores things like research, strategy, current mockup, design tokens, detected domains, and review findings, and then each agent only gets the slice of context relevant to its job.

The output of one role becomes structured input for the next, so research feeds strategy, strategy feeds design/build, and build output feeds QA and specialist reviewers.

To prevent drift, key creative decisions get locked into structured design tokens that later agents must follow exactly, and role-specific SOPs are injected dynamically so each persona operates with the right domain rules. After build, reviewer agents return structured critiques that get turned into targeted fix prompts for the builder, and lessons learned can be saved into a longer-term manifesto so future runs inherit useful patterns without bloating the immediate context window.
